Duke basketball has called off its trip to the Dominican Republic as coach Mike Krzyzewski will undergo knee replacement surgery on his right knee.

“While it’s disappointing that we aren’t able to make the Dominican Republic trip, this is a positive development for both our team and myself because it will allow us to be at full strength for the start of practice this fall,” Krzyzewski said in a statement. “After three consecutive days of working with the team, it became clear that the condition of my knee wouldn’t be sustainable through next season. The best course of action is to correct the problem now rather than later, when our team would be more profoundly impacted.”

Duke was scheduled to depart for the international trip on Aug. 17 and return on Aug. 24. The Blue Devils planned to play two games against the Dominican national team and to take part in a number of cultural activities, such as a tour of the Santo Domingo Colonial Zone and a catamaran tour.

Krzyzewski, 70, missed seven games last season after undergoing back surgery.
